take the sine of a number in typescript

To take the sine of a number in Typescript, you can use the Math.sin() method. Here's an example:

index.ts
const num: number = 3;
const sinNum: number = Math.sin(num);
console.log(sinNum); // Output: 0.1411200080598672
112 chars
4 lines

In this example, we have a variable num which stores the number 3. We then use the Math.sin() method to calculate the sine of num and store the result in sinNum. Finally, we log the value of sinNum to the console. The output will be 0.1411200080598672, which is the sine of 3.
